I review the use of auxiliary variables in capturerecapture models for estimation of demographic parameters (e.g. capture probability, population size, survival probability, and recruitment, emig ration and immigration numbers). I focus on what has been done in current research and what still needs to be done. Typically in the literature, covariate modelling has made capture and survival probab...

We derive an exact inversion formula for the attenuated Radon transform. The formula is closely related to Novikov's inversion formula, but our derivation is completely different. We also give an implementation of the inversion formula very similar to the filtered backprojection algorithm of x-ray tomography and present numerical results. http://iopscience.iop.org/0266-5611/17/1/309 “On local t...

Let IA,(B’B) A(@’, @)I < 6, where 6 > 0 is a small given number, A(@’ , 8 ) is the unknown scattering amplitude at a fixed k > 0 corresponding to a potential q(x)EL2(Bu), q(x) = q(x), q(x) = 0 in a,:= R’\B,, Bo:= {x: 1x1 < a } , @ ‘ , B E S 2 , the unit sphere. Functions qa(x) are constructed, given S z 0 and the function A,(@’ ,@) , such that 11% q/IL2(B,) 4 0 as 6 4 0. The function A,(B’, 0) ...

We identify a useful property of a program with respect to a predicate, called factoring. While we prove that detecting factorability is undecidable in general, we show that for a large class of programs, the program obtained by applying the Magic Sets transformation is factorable with respect to the recursive predicate. When the factoring property holds, a simple optimization of the program ge...

Tartrazine was examined as a possible replacement marker for rhodamine B in the Livestock Protection Collar. Test solutions were formulated in six combinations; tartrazine at 0.5% and 1.07. concentrations, with and without compound 1080, and with and without nigrosin black. Each solution was examined for persistence of color in the laboratory and when applied to the wool of dried sheep hide. Hi...

Red-winged blackbird (Agelaiu^ phoeniceus) acceptance of corn as a bait for use in ripening sunflower has been questioned. This study demonstrated that sunflower meats, sunflower achenes, and pearled barley all have potential as alternative bait carriers for 4-AP. Each can be treated with 4-AP so that individual bait particles carry dosages equivalent to those of cracked corn in the registered ...

Atrial fibrillation (AF) is the most common chronic arrhythmia, and its incidence and prevalence are expected to double within the forthcoming decades [1–3]. Currently, approximately 250,000 patients have AF in the Netherlands, corresponding to a prevalence of 5.5% in patients older than 55 years [4]. The vast majority of those patients can effectively be treated with pharmacological rate or rh...

Cell permeability controls the transportation of extracellular materials through cell membranes, which plays a critical role in drug and gene delivery. This work reports an innovative method to enhance the cell permeability through cell-bubble interactions in a high gravity field. In the presence of microbubbles, the cell membrane permeability of mammalian cells was significantly increased in t...
